Riparian zone as a main determinant of the structure of lizard assemblages in upland Amazonian forests

The use of lizards as model organisms in ecological studies is based on their success in occupying a great diversity of habitats, and some species are closely tied to the environment, which is disadvantaged by the legislation of several countries concerning land use. Our aim was to relate lizard spe...
